On the properties of temporal processing for speech in adverse environments

In this paper we report on the results that we have obtained in the application of temporal processing to speech signals. We describe what are the properties that make temporal processing an interesting and useful technique to alleviate the harmful effects that environmental factors have on speech. Though temporal processing has been used in the past, its analysis and properties have not been studied in detail. We summarize some results that we obtained in a detailed analysis, and describe a data-driven design technique to design the processing. We demonstrate a speech enhancement system which illustrates some properties, advantages, and short-comings of the technique.
